In of illustrationis shown a preferred embodiment of my invention, the numeral 10 designates the generally triangular frames of the .on their lower sides with 45 harrow sections, said framesbeing provided spaced cultivatlng spikesll which preferably ez ztend entirely through. the frames 10. The frameslO are I relatively lon e and narrow and the apex of the triangle orms the forward end of the barrow section. Substantially semi-circular brackets 12" are bolted or otherwise secured of the harrow frames.

.bars 23 are secured to the drawings, wherein for the. purpose as are also the rear portions of the frames .10 and these openings are adapted to receive pivot pins 13 which extend longitudinally The rear ends of the pivot pins are screiwthreaded to receive suitable nuts-14 which in use abut against the rear of the harrow frames and preventthe pivot pin being pulled through the openings in the frames. The forward ends of the pivot pins are bent over upon themselves to provide books 15 which are spaced infront of the brackets 12 the like device. r r

A rear cross bar 17 isarched or of substantially inverted U-shape and has its arms benttoprovide ears 18 with a plurality of.

the ears 18, abut against the inner faces of the rear portions of the frames 10. i y n A forward crossbar 20 is arched or of substantially inverted U-shape andhas armsi bent over to provide ears 21 with a plurality of openings 22 therein to receive the pivot pins. 1 The ears 21 abut against the rearward faces of the brackets 12. The cross bar 17 extendsmuch higher in the center than. does the forward cross bar 20. Suitable handle the cross bar 20 by means of suitable brackets 24 and extend upwardly and rearwardly. at an inclination.

Suitable braces 25 brace bar. with the handles 23 at points spaced from the rearof the handles.

,5 It will beseen that the cross bars 17 and 20 support the harrow sections in spaced relation, through the medium of the pivot pins i 13which may be arranged in any of the openings 19 and 22 to provide the desired spacing or angle of the harrow sections. The cross bars 17, and 20 also support the handle bars 23 and their shape permits their pasportion of each frame 10 at pivot pins 13 as seen in Figure 2.

tions,

sage over plants or obstructions, as seen in Figure 6. Thecross bars 17 and 20, handles 23 and braces 25 form a supporting framework for the harrow sections.

The pivot pins 13 extend freely through the openings in the cross bars, harrow frames and brackets and'permit self adjustment of the harrow sections. may readily take different inclinations as seen in Figure 4 where one sectionis more inclined than the other, and will therefore assume the inclination of the ground, as seen in Figures 5 and 6 where different conditions are illustrated. In. addition to serving as pivot pins the pins 13 act as drawrow sections and to the cross bars. To remove the pivot pins it is only necessary to remove the nuts 14: and withdraw the pins, and theharrow sections are then released from the cross bars. The use of the brackets 12 imparts an upwardinclination to the Other types of harrow sectionsmay obviously be used, the spiked sections being: illustrative only. While I have shown and described the preferred embodiment of my invention, it is'to be understood'that various changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit ofmy invention or the scopeof the subjoined claims.

Having thus described my invention, what I claim and'desi-re to protect by Letters Patent is:

1. In adevice of the character described, a pair of substantially triangular harrow sections, brackets secured to the forward apex of each section, asupportingframework, and a pivot pin extending through the rear of-each section and through the forward bracket on each section and pivotally connecting the sections to the supporting framework.

2. In a-device of the character described, a pair of'substantially triangular harrow secbrackets secured to the ,forwardapex of each section, asupporting framework, a

pivot pin extending through the rear of each 'SGCiLlOH and through the forward bracket on each section and pivotally connecting the sections to the supporting framework, and means to connect the forward portions of each pivot pin to a draft device.

3. In a device-of the character-described, a pair of'cross bars having their ends provided with openings, apair of'generally triangular'harrow sections, a bracket secured to the forwardportion of each-harrowsection and'provided with an opening, pivot p ns passing freely through the opening in each-bracket and through an'opening in the rearof eachharrow section, said pivot pins passing through the openings in the cross The harrow sections bars and transmit the draft pull to the har-v bars, one cross bar connecting the pivot pins immediately to the rear of the brackets on the harrow sections and the other of said cross bars connecting the pivot pins in front of the rearward portion of said harrow sections, and a handle bar connected to the cross bars. a

4. In a device of the character described, a pair of. cross bars havingtheir endsprovided with openings, a pair of harrow sections, a bracket secured to the forward portion of each harrow section and provided with an opening, pivot pins passing freely through, the opening in each bracket and through an opening in the rear of each harrow section, said pivot pins passingthrough the openings in the cross bars, one cross bar connecting the pivot pins immediately to the rear of the brackets'on the harrow sections and the other of said'cross bars connecting the pivot pins in front of the rearward por tion of said harrow sections, a handlebar connected to the cross bars, and means at the forwardends of the pivot pins for connecconnecting the pivot pins in front of the rearwardportion ofsaid harrow sections, and a pair of handle bars connected to the arched portions of the cross bars.

6. In a deVice-of'the character described, a p'airyof centrally arched cross bars having their ends'provided with openings, apair of spaced harrow sections, an upstanding bracket secured to theforward portion of each harrow section and provided with an opening, pivot pins passing freely'through the openingin each bracket and through an opening-in the rear of each harrow section, said pivot pinspassing through the openings in the cross bars, one cross bar connecting the pivot pins immediately to the rear of the brackets on' the harrow sections and'the other of said cross bars connecting the pivot pins infront of the rearward portion of said harrow sections, a pair of handle bars connected to the arched portions of the. cross bars,and said pivot pins having, hooked forward portions for connection to a draft device.

7 .In a device of-the character described, a pair of'harrow sections, brackets secured spaced harrow sec- 'rowsections and'the other ofsaid cross bars to the forward portion of each section, a supporting framework, and a pivot pin extending through the rear of each section and through the forward bracket on each section and pivotally connecting the sections to the supporting framework.

8. Ina device of the character described, a pair of harrow sections, brackets secured to the forward portion of each section, a supporting framework, a pivot pin extending through the rear of each section and through the forward bracket on each section and pivotally connecting the sections to the supporting framework, and means to connect the forward portions of each pivot pin to a draft device.
